Mutation Testing (WEEK 10)

The term mutation in software testing stand for modifying the test code and can check the existing test and detect or reject the change mutes. Mutation in Java is an additional class with a single modification compared to the original code, for example it can be the change of a logical operator  in a if section :

if( a && b ) {...} => if( a || b ) {...}

When detecting or rejecting a modification by the existing test in marked as killing a mutant. If we have a perfect test code no class mutant can survive. Testing with mutant testing can be very expensive so that is one reason why is better to write a perfect code. There are tools to create mutants and run all the tests against each of the mutants automatically. The mutation creation is based on mutation operators that are which can show typical programming errors.

This picture shows a report which list all the mutant killed by ruing the mutation testing.
Here are some of the benefits when we apply the mutation testing:

Can show all new errors to the developer
Can detect hidden defects in the structure of code
Can increase customer satisfaction index because the product can be less buggy.
Maintaining and debugging the product can be easier.


Mutation testing is very useful way to find errors and fix them and it can speedup the proses of finding bugs in the code.

Levels of testing (Week 8)

There are
different levels in a testing  process. Levels of testing include different methodologies which can be used during
the process of software testing. There are two main levels of testing :
functional testing and non-functional testing. One of my
previews posts talks about black-box testing, functional testing
is a type of black-box testing which is based on the specifications of the
software that has to be tested. The software can be tested by providing input
and then the results are examined in order to conform to the functionality
which it was meant for. Functional testing of a software is conducted on a
complete, integrated system to evaluate the system’s compliance with its
specified requirements. 
Functional testing includes five steps : 
Step 1 The
determination of the functionality that the intended application is intended to perform.
Step 2 The
creation of test data based on the specifications of the application.
Step 3 The
output based on the test data and the specifications of the application.
Step 4 The
writing of test scenarios and the execution of test cases.
Step 5 The
comparison of actual and expected results based on the executed test cases.
In order to have an effective testing process
all the above steps have to be followed and applied to the testing
policies of every organization for this reason it will make sure that the
organization maintains the strictest of standards when it comes to software
quality. This part is about testing an application from its non-functional
attributes. Non-functional testing includes testing a software from the
requirements which are nonfunctional.  Performance, Security, User
interface are some requirements examples of non-functional testing. Performance
testing is one important and mandatory testing type in terms of the following: Speed, Capacity, Stability and Scalability. Performance
testing can be either qualitative or quantitative. Security testing includes
testing a software in order to identify any gaps from security.


Security testing should ensure the below list of features: 

Confidentiality, Integrity, Authentication, Availability, Authorization, Non-repudiation, Software
data is secure, Software is according to all security
regulations, Input checking and validation, SQL insertion
attacks, Injection flaws, Session management issues, Cross-site
scripting attacks, Buffer overflows vulnerabilities and Directory
traversal attacks.
The levels of testing are important because in order to meet the functional and technical specifications  we have to follow all the steps and features that I listed above.
